The collect for this feast in our daily Mass book, Give us this day,:
As we venerate the glorious memory of the most holy Virgin Mary,
grant, we pray, O Lord, through her intercession,
that we, too, may merit to receive from the fullness of your grace.
Mary is always with us and she see what is lacking to us and asks Jesus to help. She noticed that the wine was running out at the wedding and went to her Son for help. Then she told the servants:
"Do whatsoever He tells you." I think she often says the same to me.
